Which statement is the second most critical determinant after Runway configuration?

• A. Runway occupancy time
• B. Weather
• C. Terminal passenger flow
• D. Gate turnaround time

Answer: (A)

Focus on how often the runway can be reused for each operation. Once the runway configuration is set, the next limiter on how many aircraft can pass through per hour is how long the runway remains occupied by each operation. The shorter the occupancy time, the more departures and arrivals can fit into one hour; the longer the occupancy, the fewer operations can be scheduled, even if you have multiple runways. This direct link to throughput makes occupancy time the second-most critical determinant after how the runway is configured. Weather matters, but it typically changes safety margins and possible separations, sometimes reducing capacity, rather than establishing the baseline rate per hour. Terminal passenger flow and gate turnaround affect how smoothly aircraft move through the terminal and out of gates, but they don’t govern the fundamental per-hour capacity of the runway itself in the same direct way.
